PaO2 ↓ PaCO2 is normal PaO2 may not ↓ difficult to improve PaO2 by ure oxygen inspired no help to improve PaO2 and PaCO2 by the therapy of ↑ ventilation 6/15 dead space-like ventilation refer to? hypoventilation in some alveolar ↓ ( V/Q) in part alveolar right-to-left shunt ↑ (V/Q) in part alveolar 7/15 ventilation disorder lead to? PaO2↓, no altered for PaCO2 PaO2↓, PaCO2↓ PaO2↓, PaCO2↑ no altered for PaO2,PaCO2↑ 8/15 oxygen therapy for type II respiratory failure is? low concentration in nasal tube and slowly flow high concentration in nasal tube and slowly flow low concentration in nasal tube and quickly flow high concentration in nasal tube and quickly flow 9/15 chronic obstructive pulmonary diseases may lead to? inspiratory dyspnea hyperventilation of alveolar expiratory dyspnea dead spece like ventilation 10/15 respiratory failure always refer to? severe dysfunction of internal respiration severe dysfunction of external respiration dysfunction of elimination of CO2 disorder of hemoglobin for transport gases 11/15 obstructive may be due to? ↓ pulmonary compliance alveolar ventilation perfusion mismatch restrictive of alveolar distend peripheral airway stenosis 12/15 thype II respiratory failure is diagnosed by? PaO2 < 50 mmHg(6.67 kPa),PaCO2 > 60mmHg(8 kPa) PaO2 < 60 mmHg(8 kPa),PaCO2 > 50mmHg(6.67 kPa) PaO2 < 50 mmHg(6.67 kPa),PaCO2 > 40mmHg(5.33 kPa) PaO2 < 70 mmHg(8 kPa),PaCO2 > 40mmHg(5.33 kPa) 13/15 which is the cause of respiratory failure? anemia pneumonia metheoglobinemia cyanide intoxication 14/15 which of following may result in functional shunt? embolism of pulmonary artery ↓ pressure of pulmonary artery pulmonary edema contraction of pulmonary arteriole 15/15 sedative agents overdosed lead to depressed of respiratory center and blood gases may altered? PaO2↓, no altered for PaCO2 PaO2↓, PaCO2↓ PaO2↓, PaCO2↑ no altered for PaO2,PaCO2↑
